    Heading to a service call first rhing tomorrow morning. Customer states another company has fixed the same issue at least 3 times. The issue is the wires that run through the conduit from the base to the top keep breaking. They come repair the problem but it continues to happen. Has anyone else experienced this issue and do you have a more permanent solution. I have not physically seen the unit yet.

    Wire is not wire, but I’m sure that the wires in a movable area have to be made for it. I’m not sure what spec they use, but I do know that they will have to have very fine strands and be properly routed. Perhaps MTW would be my guess.

    Thinking back on your question, Those wires are part of the heating element. And they are high temp as well. So if you try to repair inside with crimp connectors, they will never last due to the heat and oxidation. Make sure that the aluminum wire clamp isn’t bent, that the conduit is clean, never had a arc inside, and ends are smooth and sound.

    Alternately, if you have high temp heat shrink, and they are still long enough, you can solder them with a high temp electronic solder. Contains a bit of silver like the wires have as a coating.

      I was about to say the same thing.

      When parts are consistently moving, they need to be built for that purpose and most items people keep for doing routine fixes on wire connections are not built for this purpose (consistent motion and in your case heat).

      High temp wire connectors are more expensive than regular connectors but are far from being actually expensive. There is also high temp wire which is flexible which might be the right item for this job. Saw a price of approx $140 for 500ft.

    I keep I keep both high temp wire and high temp connectors in stock. I almost exclusively do hot side and now that I work for myself on the side I don’t want callbacks. The customer has spent more on repairs then the unit actually cost I’m going to take your suggestions and kind of over engineer this repair if it continues to be a problem I’m going to suggest that they just replace the unit. I was told that the customer was told by the service company that it’s a design defect and that the factory has fixed it with its new design. Don’t know how true that is.

      Good business model IMO to do it overly right so you don’t have to do it again. Even if it is a design defect on the manufactures part. That issue shouldn’t be beyond difficult to fix.

    Just wanted to postan update. The issue turned out to be the top left heating element.
